MATTRESS-ME.

,city of Sharon Hill, county of Delaware,

and State of Pennsylvania, have invented certain new and useful Improvements in Mattress-Frames,of which the following is a specification.

This invention relates to improvements in mattress frames and refers more particuare formed by angle irons and the side rails are tubular in form. 4

Among the salient ob]ects of the invention are to provide a construction in which the tubular side rails themselves form a rigid connection with the end rails without the aid of any extraneous fastening devices such as bolts, rivets, screws and the like; to provide a construction in which the ends of the tubular side rails have flattened ends projecting through and secured in sultable slots formed in the end rails; to provide in a construction of the character referred to means for positively preventing any lateral displacement of the rail members and thus insuring them from ever getting out of alinement; to provide a construction in which the side rails are secured to the end rails in such a way as to avoid leaving outa standing portions which would have a tendency to catch in the bed clothing or the like; to provide a construction in which the flattened end of the tubular member, projecting through the slot in the end rail is so shaped and proportioned that when the protruding end is bent down to lock the parts together a smooth exterior surface is resented; to provide a construction which is adapted touse with either a woven wire fabric or with a link fabric; to provide a construction which is economically manufactured and at the same time has all the requisites necessary in a construction of this character; to provide in a construction of the general character referred to, an improved form of riser or bracket which rests on the side rails of the bed frame and forms the support for the mattress frame; to provide a construction of. the character referred to which is simple and economical in form and is secured to the side rail without the necessity of any clamping rings, rivets, bolts or the like; and in general to provide Specification of Letter: rmm.

an Improved construction of the characte referred to. V In the drawings:

Figure 1 is a side elevation of a mattress frame embodying my invention.

Fig. 2 is a top plan view thereof.

Figs. 3 and 4 are enlarged detail views of one of the side and end rails respectively.

Fig. 5 is an enlarged side elevation, partly in section, showing one of the side and end rails in assembled position.

Fig. 6 is an enlarged cross sectional view showing the manner of fastening the riser or supporting brackets connected to theside I rail.

Fig. 7 is an end elevation of the riser or supporting bracket before it is attached to the side rail.

Fig. 8 is a fragmentary sectional View showing one of the side and end rails partially assembled.

Describing in detail the particular embodiment of my invention shown in the drawings, 1 designates the mattress frame which comprises the end rails 2 and 3 and the side rails 4 and 5. The latter are preferably formed of tubular stock and are each bent near their ends to provide upwardly angling portions 6 and 7, the extreme ends of which are flattened as shown at 8. The particular construction of this flattened end portion and its assembly to the end rails forms an important feature of my invention. As shown in detail in Figs. 3 and -8 the flattened end 8 of each side rail isnotched out at the corners to rovide shoulders 9 and 10 while projecting yond the plane of these shoulders is a double width thickness of metal, the upper wall 11 of which has a beveled edge 12, while the lower wall 13 projects beyond the plane of the beveled edge of the upper wall. In assembling the parts the end walls 11 and 13 are inserted through the slot or aperture 14 formed in the vertical flange 15 of the end rail. This slot. is referably located just below the lane 0 the upper flange 16 of the angle iron so that into substantial parallelism with the vertical flange of the end rail.

The novel construction and proportioning of the projecting ends 11 and 13 is such that when these ends are bent down a substantially smooth exterior surface 17 is presented and both ends lie substantially in the plane of one thickness of the metal which forms the tubular side rail. This manner of securing the side and end rails not only secures a rigid connection which will prevent any longitudinal or lateral play between the parts but also provides a mimmum projection beyond the plane of the outer surface of the end wall.

The mattress frame as an entity is supported upon the bed frame by means of risers or brackets 18, the construction and assembly of which are also features of the invention. In detail the bracket comprises a bearing surface 19 adapted to rest upon the side sill of the bed frame and a socket portion 20 having on its lower inner surface an inwardly projecting lug 21 and at its upper end-a projecting lip 22 extending tangentially from the normal circumference of the socket. This novel arrangement permits of the lug 22' being inserted through an aperture 23 drilled or otherwiseformed in the lower surface of the side rail. When thelug is so inserted the lip 22 is forced downward around the tubular side rails to the position shown in full lines in Fig. 6, and the assembly is completed. The construction and assembly of both the end and side rails and the risers and supporting brackets is such that no extraneous fastening devices such, as bolts, screws or the like needbe employed and as the spring or woven fabric24 can be secured .directlyto the end rail throughapertures 25 formed in the flanges thereof, the construe tion is one that embodies a minimum of parts and tends to greatly reduce both the cost of construction and assembly.

While I have shown and described a tubular side rail it is obvious that rails. of a different cross section might be employed and various other changes made in the detailed construction and arrangement of parts without departing from the scope of my invention which I do not desire to limit except as specified in the appended claims.

I claim'as my invention:

1. In a mattress frame, the combination with a tubular side rail, of means for supporting said side rail on a bed frame comprising a riser or supporting bracket having C. L. WAsoHER, THEO. H. MOOALLA.
